You need to flash the engineering abl via QFIL, then enter fastboot and write the fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
hola soy nuevo en esto y escribo español, podrias ayudarme mi celular es atyt g850um pero la version es g850um10o quiero actualizar ya sea android 10 o 11, me podrias ayudar de como lo lograste.
Gracias a todos los demás chicos aquí que han hecho un desarrollo útil para domar esta hermosa =)
LG ha hecho las cosas difíciles al flashear roms personalizadas e incluso en stock con esta nueva cosa OPID. Nos evita el parpadeo cruzado, pero hemos podido usar TWRP y cambiar el sistema y algunas otras particiones para tener una rom diferente. Tuvimos que hacer algunos cambios en la partición OP usando el editor HxD.
Pero ahora, a través de este tutorial, podemos actualizar cualquier rom sin la necesidad de cambiar OPID en la partición OP. Además, no es necesario rootear o desbloquear el cargador de arranque.
Tuve éxito al hacer esto en algunos G8 (LMG820UM), ¡pero NO SOY RESPONSABLE DE NINGÚN DAÑO A SU TELÉFONO!
Si continúa leyendo las siguientes instrucciones, realmente acepta el riesgo.
Change the attribute of "UI_Config.lgl" to read only for the first issue.I initially had all options on LGUP but at some point had only 3 (refurbish. Upgrade and FOTA upgrade) I just went ahead and hit the start button and it went through no mismatch error or something....but the most issue I got is device blinking on and off for a whole while in between the first greet message of "LG V50 Thinq"
no way changed attributes to read-only yet I still have 3 options to choose fromChange the attribute of "UI_Config.lgl" to read only for the first issue.
I had no V50 and also I didn't do this on G8 but you can try to flash "vbmeta" on both sides, a and b using the below code (supposed your vbmeta has .bin extension). It may help!
Remember to use engineering bootloader. And, you can dump vbmeta from your phone.fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta_a.bin
fastboot --disable-verity --disable-verification flash vbmeta_b vbmeta_a.bin
Hi. I am using LG V500N LgU+ with imei 0 and ntcode 0. I fixed imei 0 according to the instructions of bro netmsm, now only ntcode 0 so no mobile signal. I changed the vbmeta file for both partitions a and b in mode 9008 but could not overwrite another cust_path_mapping.cfg file.You need to flash the engineering abl via QFIL, then enter fastboot and write the fastboot --disable-verity --disable-verification flash vbmeta_a vbmeta.img
fastboot --disable-verity --disable-verification flash vbmeta_b vbmeta.img
or try to flash my Vbmeta already patched. As I said, I have lg v500n lgu +
do not forget to make a backup of the native abl. you must restore it after you finish working in fastboot
Someone has been successful to modify NT-Code this way: Flash Korean A11. Dial *#546368#*500#. Go to SVC Menu > MID Info and change NT-Code.Hi. I am using LG V500N LgU+ with imei 0 and ntcode 0. I fixed imei 0 according to the instructions of bro netmsm, now only ntcode 0 so no mobile signal. I changed the vbmeta file for both partitions a and b in mode 9008 but could not overwrite another cust_path_mapping.cfg file.
Do you have a telegram? Help me. Thank you very much.
Sorry, I used google translate to answer you because my english is bad.
I tried changing in MID info but only IMEI can be changed but not NTCODE. So I'm just trying to follow your guide marahuan. If you do it your way marahuan and fix the mobile signal, that would be great.
I finally got it working but device is bricked I think just keeps blinking on and off on the LG V50 logo and does nothing repeatedly. I've tried using stock ROM to flash no way about four of them any help on this
This is my isssue as of now... i tried the crossflash followed all instructions laid out but ended up bricking my device its a V500N30c-SKT-KR I tried using a V500N30b file to cross flash though I didn't get the option for PARTITION.DL so I just used the refurbish. i finally got all options on LGUP to work (which you gave) and I tried redoing the steps no way still stuck on a blicking screen someone suggested the file is bad and I should flash original rom with same region and code which I did no way (somehow I think the file got corrupted while I downloaded) am getting an A10 file with same region. i pray this works and downgrade me else am F*CKED. plx advice anyone on how to get my device back to live (still got download and EDL mode working) got the firmware from https://lgrom.com/firmware/LMV500N/SKT/V500N30C_00/9310 (hope am not breaking anything posting a direct link)
No, not everything will work. The camera app on the kor rom is for the 3 rear lens version (only Kor has that). I've tried a few things to get that app to work with 2 lens version, or install the apk from us version, or modify configs... none of them worked.
I flashed and it is locked.Has anyone successfully flashed Sprint V50 to A11 using this guide and kept bootloader locked?
From information gathered from this guide, there is a need for another modem to get signal/data. Also, getting opid mismatch error is almost given since OP is not modified and intention is to keep this clean with booloader still locked to avoid problems with many apps detecting tampered device and refusing to work.
More info is needed but this is all I got from this thread in regards to Sprint V50 and locked bootloader.
Bank apps works without problem, about crypto wallets I don't know because never used that, safety check pass everything, there is not opid mismatch error. The Eu ROM have Hidden Menu with field test to activate voLTE so the system is smooth and even can use velvet 2 pro apps in the phone, so I'm very satisfied only con I found is the Everytime I want to update to newer software version I have to reinstall and setup everything because I can't make a backup in mobile switch but that's only a spending time problemThank you very much for a very valuable and technical info about it! I have updated my original post to reflect on your findings.
When/if you can, please tell us more about functioning of any apps that checks device security, like bank apps, or crypto wallets or some authenticators, are they working? Also about op id mismatch error, is it present and how in general you are satisfied with your crossflashed Sprint V50?
I would like to know the following:
(1) first, MAKE A FULL BACKUP OF ALL PARTITIONS; and I mean it!!! How, exactly, does one make this full backup? How does it get restored if needed?
(2) 1. Make a backup of and erase these 5 partitions: FTM, Modem_A, Modem_B, SID_A, SID_B, OP_A, OP_B. What does this mean, exactly? What tool is being used for this?
(3)If you are in Spring or other platforms you will get the message whether to change the model or not. Of course you know what to do =). I do not know what to do. It is not helpful to write such a vague, obtuse instruction.
